For the grease used under the ancient conditions, it is known that, for example, an organic rust inhibitor is added to the urea grease (% of the urea light) in which the oil is used as the base oil. For example, refer to Patent Documents 1-3 to 3) ^ This case prevents rust by adsorbing an organic rust inhibitor on a metal surface to prevent direct contact of water and oxygen with metal. Dan, 3 However, such as continuous casting equipment, when the water containing corrosive ions in the water: into the grease and the bearing is placed for a long time, the previous grease can not inhibit the rust, due to care The ratio of bearing scrap rate is large. In the case of a grease composition which exhibits excellent rust resistance even in an environment in which a large amount of water containing corrosive ions is mixed, Patent Document 4 describes a grease composition containing a base oil, Diurea thickener as shown in the following formula: RNH-C0-Dragon-(tetra)-CH2-C6H4_NH-C0-臓2 (wherein R1 and R2 are phase 319666 5 200819529, same or different carbon An alkyl group having 6 to 30 atoms, an aryl group having 6 or 7 carbon atoms, or a cyclohexyl group, a metal sulfonate, at least one compound selected from the group consisting of succinic acid and a succinic acid derivative, Naphthenate; (naphthenate), and surfactant.

Suppresses rust and can be caused by rust: Cheng: The bearing scrap rate is greatly reduced. Therefore, it is particularly suitable as a bearing grease such as a continuous casting equipment bearing or a rolling mill bearing which is splashed with water and 7 which is mixed into the grease so as to be easily rusted. Prevention = The grease composition of the present invention can be inspected at any time because the bearing is not discolored due to the lack of reactivity. 319666 7 200819529 [Embodiment] The base oil to be used in the grease composition of the present invention may, for example, be an oil, a vinegar-based synthetic oil, a synthetic oil, a synthetic hydrocarbon oil or the like, and these may be: -: t mixed Two or more types are used. In particular, mineral oil is preferred, and mineral oil having a dynamic viscosity of 1 (10) to 500 _ ν is preferred. The grease composition of the present invention is represented by the formula (1).

Acid #5 salt: Dinonylnaphthalene acid sour lime salt: Dinonylnaphthyl zincate surfactant: sorbitan trioleate (hlb=18) .* Results from Table 1 It can be understood that Example 1 of the present invention is a grease composition containing a base oil, a cone f 诏 as shown in the formula (1), a surfactant, and succinic acid. Since the derivative, the metal sulfonate, and the benzobisazole compound have excellent rust resistance and copper plate corrosion resistance. Φλ In contrast, from the results shown in Table 2, Comparative Examples 1 and 2, which do not contain a succinic acid derivative, Comparative Examples 3 and 4 which do not contain a metal sulfonate, and Comparative Examples which do not contain a surfactant are known. The grease compositions of 5 to 7 were inferior in rust resistance and corrosion resistance of the copper sheets, and the lubricating wax compositions of Comparative Examples 8 to 10 which did not contain benzotriazole were inferior in rust resistance and large in rotiness of the copper sheets. 14 319666
